EXPLOSIONE1\TGINE Specification of Letters Patent,

Patented June 15, 1909.

Application filed April 20, 1908. Serial No. 428,148.

Be it known that I, HARRY M. CRAMER, a l citizen of the United States, residing at the city of Lansing, county of Ingham, State of Michigan, have invented certain new and useful Improvements in Explosion-Engines, of which the following is a specification;

' This invention relates to improvements in explosion engines.

The main object of this invention is to provide in an explosion engine an improved means for lubricating the valve actuating cam and the gear connections of theorank shaft thereto which shall not only effectively lubricate the parts, but one which collects the lubricant so that it is not likely to drip or runout upon the exterior parts of-the engine.

Further objects, and objects relating to structural details, will definitely appear 1 accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a partof this specification, in which,

Figure 1 is a side elevation of a structure one of the balance-wheels and the governor mechanism proper and also the gear casing being removed to more effectively show the relation of the parts. Fig. 2 is a detail central vertical section 'of the structure shown in Fig. 1.

In the drawing, similar numerals of reference refer to similar parts in both views.

Referring to the drawing, the base 1 is, of any suitable construction, and is preferably designed to serve as a storage for the liquid hydrocarbon. The crank shaft casing 2 is mounted on the base and is provided with suitable bearings 3 for the crank shaft 4. The crank shaft casing is preferably adapted to serve as a receptacle for the lubricant. The cylinder 5 is mounted on the crank shaft casing, the inner end of the cylis connected to the crank shaft in a suitable manner. Countcrweights, as 7, are preterably provided for the crank shaft, and

of the threaded plugs 15.

these counterwcights and crank shaft arms,

2 as the crank shaft is revolved, are adapted to strike into the lubricant and atomize or break up the same, so'that the air Within the crank shaft is effectively charged with the lubricant. On the hub 8 of the balancewheel 9 is a pair of inwardly-projecting arms 10 on which the governor weights 11 are pivotally mounted. The inner ends of these arms are engaged with the grooved collar 12, 'slidably mounted upon the crank shaft. The governor weights are held normally inward by means of the ,springpressed pins or' blocks 13, the pressure springs 14 therefor being preferably 'arranged in suitable chambers provided there for in the hub of the balance-Wheel. The tension of the springs is regulated byineans These parts are all substantially such as are shown in my application for Letters Patent filed November 19, 1906, Serial No. 344,039

The exhaust valve actuating plunger 16 the exhaust valve not being shownis actuated by a cam 17, the plunger beingprovided with a roller 18 at its lower end adapted to rest normally upon the cam.

When the s eed of the en ine exceeds a predetermined point, the collar 12 is drawn outwardly by means of the governor weights,

which allows the upper end of the lever'19 toswing in until the catch block 20 thereon engages the catch 21 on the valve-actuating plun er, holding the plunger in its elevated position so that the valve is not fully actuated and consequently the engine is not charged. The lever 19 is thrown into its engaging position by means of a coiled spring 22. The cam 17 is connected by the gears 23 and 2a to the crank shaft, the gear 24 being mounted on the crank shaft and the gear 23 being mounted on the hub of the cam. The journal 25 for the cam is provided with a conduit 26 which opens into the crank shaft casing, so that, when the engine is in operation, the arms and balanceweight of the crank shaft strike into the lubrlcant, effectively atomizing the same, and

on the outstroke of the piston, a portion of the lubricant-laden air is forced through the conduit 26 which opens to the bearing surface of the journal to properly lubricate the journal. The bearing 27 for the plunger rod is also connected to the crank shaft casing by means of .a suitable lubricant conduit, as 28. The journal 25 and the lower end of the bearing 27 for the valve actuating plunger are, arrangedin a gear casing {28 for the connecting gears for the camtd ,the crank'shaft. This gear. casing is also ada ted to serve as a lubricant receptacle so t at all of the-waste or excess lubricant passin from the valveactuating cam andv the vave plunger rod, bearings is collected in the crank shaft casing and the gearssuitably lubricated thereby, thus effectively utilizing'the Waste from the cam and plunger rod bearings. I

Having thus described my invention, what I claimas new and desire to secure by Let ters Patent is: Y

f1. In anexplosionengine, the combination with a cylinder, of a piston; a crank shaft; a closed crank shaft casing adapted to serve .as an oil reservoir; an exhaust valve; a plunger rod-for actuating said exhaust valve; a cam for actuating. said plunger; connecting gears for said cam to said crank shaft; a journal on which said cam and one of said connecting gears are mounted, sa id journal having a conduit therein opening into said crank shaft casing, said conduit being opened to the bearing surface 1 with a cylinder, of a piston; a crank shaft;

. shaft; a journal on which said cam and one a closed crank shaft casing adapted to serve as an oil reservoir; a valve-actuating cam; connecting gears for said cam to said crank of said connecting gears are mounted, said ournal havlng a conduit there1n. opening into said crank shaft casing, said conduit being opened to the bearing surface of said journal; and a gear casing for inclosing the said cam and said connecting gear therefor, the said gear casing being adapted to serve as an o'ilreservoir'arranged to-collect the lubricant delivered from said cam bearing "casing adapted to serve as an oil reservoir; a-

cylinder openinginto said casing at its inner end; an exhaust valve; a plunger for actuating said exhaust valve; a cam for actuat ingsaid plunger; a journal therefor mounted on said crank shaftcasing; gear connections for said cam to said crank shaft; a gear casing inclosing said cam and gear, the lower portion of said gear casing being adapted to serve as an oil reservoir; a bearing for said plunger mounted on the top of said casing; and oil conduits leading to the bearings of said cam and plunger opening into said crankshaft casing whereby the lubricant is su plied to said bearings and collected in said gea'r casing to lubricate said gears, as specific 4 with a crank shaft, of a closed crank shaft casin adapted to serve as an oil reservoir; a

4. In an explosion engine, the combination cylin er opening into said casing at its inner 7 end; a valve; a valve actuating cam; a ]0l1I.-

nal therefor mounted on said crank shaft casing;-gear connections for said cam to said crank shaft; a gear casing inclosing said cam and gear, the lower portion of said gear casing being adapted to serve as an oil reservoir; and an oil conduit leading to the bearing of said cam and plunger opening into said crank shaft casing, whereby ubricant is supplied to said bearing and collected in said gear casingv to lubricate said gears, as

specified.

In witness whereof, Ihave hereunto set my hand and seal in the presence of two witnesses.
